Linking to sites that cripple navigation

[Jerry Kuntz]

I recently received a complaint about a site that we cataloged in
KidsClick!. The site in question is the Brainium:
http://www.brainium.com/
The complaint was that the jscript at this site disabled the Back button,
making it impossible to go back to a search result set in KidsClick! It was
suggested that we both complain to Brainium web masters and--failing
that--remove it from the KidsClick! catalog.
Web4libbers:
1) Could someone tell me the exact jscript command that is doing this? I
don't see it.
2) What do you think of deselecting sites in a library-managed web guide
that intentionally cripple normal browser commands?
